Take a look at the best thermal scope for hunting in total darkness. It’s number one because of its reputation for dependability and complete rack of the most useful features. But it comes at a cost.

Overview

If you want to go top-of-the-line, this may be the best thermal scope for the money. It has all the great features of our top pick. The max zoom is 15, rather than 18. And the battery life is a couple hours shorter. That’s basically it. But you can save hundreds with this scope.

The reviews for this one are similar to the ones for our top pick. That’s not odd, considering how similar they are. There really haven’t been any complaints about the battery life or zoom, which are the only differences.

ATN has made it possible for even folks on a tight budget to use a thermal scope. This one is about a quarter of the price of the premium models. It’s possible to put together a rifle/thermal scope combo for less than $2000. And you don’t have to give up the iamous ATN quality to save money. It’s built just as solidly as their other scopes, but some key features are missing.

You can’t record or stream at all. And the thermal sensor is a bit less sensitive. But it’s still good for distances of up to 200 yards.

As you may have guessed, the weight and price of this scope are what people talk about most. This is actually one of the top picks for sportsmen who are just starting to use a thermal scope.

More experienced night hunters are surprised that it feels so light. They like that they it doesn’t add much to the weight of their rifles. And they like it so much that some consider it the best thermal scope for coyote hunting due to its good range and range finder.

Overview

A thermal hunting scope should be easy to use when it counts. And that’s when you’re preparing to take a shot. Pulsar’s Thermion XM allows you to choose between 13 reticles. Choose from classic crosshair, post and everything in-between.

And you can set your zoom to the distance you intend to shoot and park that image in the corner. Then you use the scope’s full field to keep watch over your target. Having that set can save critical seconds when they count.

The zoom functions bring a lot of people in. Once they buy and mount their new scope, they spend some time browsing the different reticles and playing with the picture-in-picture feature. It’s fun to watch people see how useful that is.

They talk about how easy it is to track game through the scope, the take a quick shot when movement stops. Since you’re already zoomed in, there’s no need to fool with the zoom when they prey stops.

Overview

Digital contrast enhancement is a rare and expensive feature to find on a thermal imaging scope, but this one has it. It helps pick out smaller, more distant targets. That can help your accuracy. Another great thing is the small size and light weight. It’s a big plus on long hikes. Compare the weight to a light binocular. But, alas, the price makes it a dream for many of us.

People who wear gloves wish that this scope had regular turret controls rather than the thumbsticks. You need to feel the sticks to use them accurately, and even thin gloves can be cumbersome in this respect.

But all of the other features check out. It isn’t a bare-bones scope. You’ve got the range finder and choice of reticles. What you’re losing, other than the weight and size, is recording capability. Many feel that it isn’t worth the price, but its fans say that you can’t find another scope built like this at any price.

Overview

When we see a thermal vision rifle scope above five grand, we look to see how the price is justified for the average rifleman. In this case, we found that the high price comes from features that only people with a lot of experience with thermal scopes will benefit from.

This scope has the capability of tracking and displaying moving targets, like a running coyote. That’s a shot that not many would even be interested in attempting, but experts may consider this scope to be oe of the most advanced on the market.

We found some rave reviews from highly seasoned night shooters. Some of the features, like the high refresh rate, scanning range finder and triple zero settings, are useful only for people who have experience using basic thermal scope features. So they can be either confusing or useless to the average shooter, but they can greatly enhance the accuracy and performance of more capable night marksmen.

Furthermore, we created a list of reviews on scopes for squirrel hunting , these scopes are budget-friendly and ideal for hunting to small animals like a squirrel .

Factors To Consider When Choosing A Thermal Scope

Would you like to know what factors we took into consideration as we picked the tops? Here’s the things you need to keep in mind and the answers to the questions that people ask us the most.

Image Sensor

This isn’t the display resolution. This has to do with the way the electronics process the infrared light and process it into an image. But, like screen resolution, the higher numbers are better. Choose at least 320×240. Anything above that is considered sensitive enough to provide a detailed image.

Detection And Recognition Range

The detection range signifies at what distance the sensor picks up heat to tell you that something is there. Recognition range refers to the range at which you can tell what kind of animal you are looking at. Consider the recognition yardage your maximum shooting range.

Zoom

The zoom basically works the same way that it does in a regular scope. The longer the distance you’ll be shooting, the more zoom you can use. Moat have variable zoom. Look at the zoom of the daytime scope you currently use, and get a thermal scope with comparable zoom capabilities.

Range Finder

You don’t want to go fumbling around with a separate range finder when an opportunity presents itself. That’s why integrated range finders are so useful. They work with a laser beam to provide you with a reading that is accurate to within one yard at a range of about 1000 yards.

Weight

They can weigh between a pound and up to five pounds, depending mostly on the thickness of the tube and the size of the battery. But why is it important? It really isn’t unless you carry your rifle for hours at a time. If you are a still hunter or normally take a long hike to get to your spot, you may be looking for a lighter scope. Think about how much a thermal scoped AR can weigh. A light rifle is a plus in many situations.

Warranty

This is pretty self-explanatory. Longer warranties protect your purchase against defects for a longer period of time. The gold standard is three years. Gone are the days when this kind of scope came with a lifetime warranty. But you can still find five-year guarantees if you are inclined to look.

Price

None of them are cheap. Budget scopes go for around $1000 at the minimum. The average is between $3000 and $4000. You can find them over ten grand. It all depends on the special features. Do some comparison shopping, like we did.

Battery Life

You’ll probably use your thermal optic scope as a field scope as well. So you’ll actually be using it for hours, not just a few seconds. Check out how long the battery lasts. Lighter scopes usually have a life of around four hours. But bigger, heavier scopes can give you up to 20.

Audio/Visual Recording And Streaming

Many scopes have the ability to record onto an SD card. Some can even livestream onto the internet. Would you like to record your hunt? You’ll pay a little extra, but it would be nice to save those memories. You can even use the footage as a self-training video. If you go this route, you might as well go high res.

Thermal Scope FAQs

It depends on the sensor. A 640×480 sensor will show you a thermal signature out to 2000 yards. Lower sensitivity means shorter detection ranges. But the recognition range is what you should consider the most. That’s the distance at which you can shoot, given all other conditions are perfect.

They are legal on a federal level, but some local governments restrict their ownership to police. Check your local regulations. And be very careful if you plan to use one for hunting. It is a crime to hunt at night in some areas, with or without a thermal scope.

They convert invisible infrared light, which comes from heat, into an image that you can see.

They can be switched from day to night mode in the settings. This is convenient and eliminates the need for separate scopes for day and night hunting or patrol.

Conclusion

ATN makes some good thermal scopes, and three of them made our list. Their Thor 4 is the all-around best. It is loaded with useful features and comes at a good price. ATN’s Thor LT carries many of the same useful features, but only costs around $1200. It’s our budget pick. If you want a very light scope, Trijicon’s Teo Reap-IR weighs under a pound and a half, but it is rather expensive.

Now that you know what to look for and have seen the best thermal scopes, why not get yours today?
